That's weird! Looks like the vertex normals are failing; what is mesh.vertices.shape and mesh.faces.shape? If you run mesh.process(validate=True) first (which will remove degenerate faces and do some other cleanup) does this still occur?

@mikedh I found it was caused by torchgeometry some func API changed, it seems torchgeometry move into kornia, but their api need one less dimension input caused dimension fails.
